RELATED APPLICATION

The current application is related to (continuation of) a prior provisional application U.S. 61/571,029, filed on Jun. 20, 2011, with the same inventors and a similar title, taking benefits of all teachings and earlier filing date of that application. A reassignment to D4 Brands, LLC has been made and can be referred to by the EPAS ID#: U.S. Pat. No. 1,761,603.

BACKGROUND OF THE INVENTION

Belts are commonly used by uniformed professional field personnel (e.g. law enforcement, tire, park department, search and rescue, private security, utilities personnel, military, etc.) to carry equipment. They are known as duty belts in the industry. In the most common configuration, the duty belt and inner belt are used together. The user threads the inner belt (also known as a trouser belt) through the belt loops of the user's pants. Commonly these have one half of a Velcro assembly on the outward facing surface. The duty belt itself is a wider belt positioned over the inner belt, outboard of the pant belt loops (FIG. 1). The duty belt is typically 2 or 2.25 inches wide. The duty belt attaches to the inner belt by means of the other half of the Velcro assembly. Because of the weight of the loaded duty belt and the fact it is critical that the uniformed professional does not become separated from his/her duty belt, supplemental mechanical straps known as “keepers” are used that wrap around both inner and duty belts to ensure that they are firmly attached to one another. Still on other belts, there is no Velcro used at all between the inner and the duty belt. The keepers are the sole retention mechanism between the two belts in that configuration.

Equipment is carried on the duty belt by accessory holders that are threaded on the duty belt. Users commonly carry a large number of accessories and fill up almost all of the available space around the circumference of the duty belt. Because users typically spend a large amount of time traveling in vehicles in a seated position, accessories located between the user and the seat cause discomfort and can lead to long term back issues. It is important that the number of accessories located on the small of the back are minimized. Existing duty belt buckles take up a large portion of space on the front of the belt and have a large area in which the user cannot place accessories, forcing the user to locate accessories near the small of the back.

A typical duty belt Fastex type buckle is shown in FIG. 2 a. To open the buckle, the center button must be pressed prior to squeezing the opposing buttons on either edge of the buckle (FIG. 2 b). The belt material threads through the Fastex buckle, is folded back onto itself and attaches back to itself by means of a Velcro assembly. This creates a thick area in the belt assembly where belt accessories cannot be placed near the buckle because of interference. The buckle must be separated from the belt in order to thread on belt accessories, which results in loose parts that can be dropped and lost (FIG. 2 c). Before accessories are put on, a free slider that is used to retain the folded over portion of the end of the belt must first be removed. This results in more loose parts and is prone to errors for users who do not frequently reconfigure their belts.

Another popular style of buckle for a duty belt, known as a traditional buckle, is shown in FIG. 3 a. To assemble the belt, the buckle is slid onto the belt (FIG. 3 b) and the buckle prongs are engaged with the belt (FIG. 3 c). The end of the belt is threaded through the other half of the buckle (FIG. 3 d) and the central bar on the buckle engages with the prongs on the distal end of the belt (FIGS. 3 e to 3 f). A stud which is integrated on the hook end of the belt is then pressed through a hole on the buckle end of the belt (FIG. 3 g). A keeper is then slid over the free end of the belt (FIG. 3 h). Disadvantages with the design are similar to the Fastex buckle in that the buckle must be removed in order to put on accessories, resulting in a loose part that can be lost. Additionally, accessories cannot placed near the buckle due to the thickness of the buckle assembly.

Users often need to add or remove layers of clothing, which requires that the duty belt be adjusted in circumference to maintain a correct fit. Both of the duty belts described above have the disadvantage in that the user is required to disassemble the duty belt and separate the buckle from the belt to adjust the circumference.

There exists a need for a duty belt and buckle which allows for accessories to be positioned closer to the front of the belt, makes it easier for accessories to be added or removed, and makes it easier for the circumference of the belt to be adjusted, all of which result in a belt that is more usable and more comfortable.

SUMMARY OF THE INVENTION

Accordingly, the advantages of one or more aspects of the present invention are:

-   -   a buckle for a duty belt which has a low profile and narrow         width that allows for accessories to be placed very close to the         front of the belt;     -   a buckle for a duty belt which has a security feature to prevent         it from becoming inadvertently detached;     -   a buckle for a duty belt which requires no disassembly or         removal of parts when installing accessories or adjusting         circumference.

One embodiment features a duty belt, a buckle body and a cover. The buckle body is fixed to one end of the duty belt and has a mating element on the backside of the buckle body which engages with an attachment member on the distal end of the belt. The cover features interlocking securing protrusions that prevent the mating element from disengaging with the attachment member on the distal end of the belt when in a closed position. The narrow width of the buckle, and engagement with the distal end or the duty belt allows for accessories to be placed near the front of the belt, reducing the number of accessories located near the back of the user and making the belt more comfortable for the user. A plurality of attachment members exist on the distal end of the belt which allow the circumference of the belt to be adjusted without diassembling the buckle from the duty belt.

Other advantages of one or more aspects and a full understanding thereof will be apparent from a consideration of the following detailed description and claims taken together with the accompanying illustrations.

DETAILED DESCRIPTION First Embodiment

One embodiment of a duty belt and buckle is illustrated in FIGS. 4 to 6. The duty belt and buckle comprises two primary components: a duty belt 10 and a cover 12. A buckle body 14 comprises an attachment point 22 and a mating element 18. Attachment point 22 fixes buckle body 14 to a first end of duty belt 10. Mating element 18 provides a means for engaging with attachment member 16 on the distal, second end of duty belt 10. Mating element 18 extends from buckle body 14 such that, when engaged with attachment member 16, buckle body 14 is prevented from moving in one direction axially along the belt and in both directions that are perpendicular but in plane with the belt. Attachment member 16 is inserted through the open end of mating element 18 (FIG. 5 a). The second end of duty belt 10 features multiple attachment members 16 spaced along the long axis of the duty belt (FIG. 4), enabling the circumference of duty belt 10 to be adjusted. Attachment members 16 do not add any thickness to the second end of duty belt 10 so that accessory holders can be easily added and removed from the belt. Cover 12 is attached to a hinge 24 on buckle body 14 and pivots with respect to buckle body 14. Cover 12 features securing protrusion 20 (FIG. 6 a) which interlocks with mating element 18 when cover 12 is closed. When cover 12 is in the closed position, securing protrusion 20 engages with attachment member 16 to prevent buckle body 14 from moving in the other, previously unconstrained direction along the axis of the belt. Cover 12 snaps into a closed position with buckle body 14 such that it cannot open without a predetermined force applied by the user along the arc of rotation. Cover 12 has a lever end that allows the user to apply a force along the arc of rotation with their fingers and rotate cover 12 with respect to buckle body 14. The narrow width of the duty belt buckle allows more accessories to be placed near the front of the belt.

The belt, buckle body, cover and other components can be made of material such as polymers, metals, cellulosic materials, ceramics, glass, biomaterials, nanomaterials, and composites.

Operation

To use the duty belt buckle, the user first places the duty belt around their waist. The user opens cover 12 (FIG. 8) and engages mating element 18 of buckle body 14 (FIG. 9) wt attachment member 16 (FIG. 10). The user chooses the attachment member 16 which creates a duty belt circumference that provides a comfortable fit around their waist. The user then closes cover 12, which snaps into a closed position with buckle body 14 (FIG. 11).

To remove the duty belt, the user first applies a force to the lever end of cover 12 along the arc of rotation, disengaging cover 12 from the snap engagement with buckle body 14. The user rotates cover 12 to disengage securing protrusion 20 from attachment member 16. The user then must move the duty belt buckle in the opposite direction of removal to disengage mating element 18 of buckle body 14 from attachment member 16.

Should the user need to add another or subtract a layer of clothing and change the circumference of the duty belt, the duty belt removal operation is followed as detailed above. The user then makes the circumference of the duty belt smaller or larger by choosing the attachment member 16 which provides a comfortable fit around their waist and follows the duty belt buckle engagement operation as detailed above. No disassembly of the duty belt buckle is required and no loose parts are separated from the duty belt that can be lost.

Alternative Embodiments

There are various possibilities with regard to the configuration of the duty belt buckle. The buckle body can employ a plurality of mating elements 18 for engaging with a plurality of attachment members 16 on the distal end of the duty belt.

The first end of belt 10 can comprise a mating element 18 which provides a means for engaging to attachment member 16 (FIG. 12 a). When engaged with attachment member 16, mating element 18 prevents the first end of belt 10 from moving with respect to the second end of belt 10 in one direction axially along the belt and in both directions that are perpendicular but in plane with the belt. Cover 12 is pivotally attached to the first end of belt 10 and comprises a protrusion such that, when closed, it prevents the first end of belt 10 from moving with respect to the second end of belt 10 in the second direction axially along the belt (FIG. 12 b).

Alternatively, mating element 18 can prevent the first end of belt 10 from moving with respect to the second end of belt 10 in one direction axially along the belt and in one direction perpendicular but in plane with the belt (FIG. 13 a). Cover 12 is pivotally attached to the first end of belt 10 and comprises a protrusion such that, when closed, it prevents the first end of belt 10 from moving with respect to the second end of belt 10 in the second direction axially along the belt and in the second direction perpendicular but in plane with the belt (FIG. 13 b).

In another embodiment, cover 12 is pivotally attached to the first end of belt 10 and comprises a protrusion such that, when closed, it prevents the first end of belt 10 from moving with respect to the second end of belt 10 in both directions axially along the belt and in one direction perpendicular but in plane with the belt. The first end of belt 10 is positioned over the second end of belt 10 so as to prevent the first end of belt 10 from moving with respect to the second end of belt 10 in the second direction perpendicular but in plane with the belt.

CONCLUSION, RAMIFICATIONS, AND SCOPE

Accordingly, the reader will see that at least one embodiment of the duty belt buckle provides a lower profile and narrower width, allowing the user to position more accessories on the front of the duty belt, providing better access and more comfort. The duty belt buckle has the additional advantage in that it cannot be inadvertently disengaged from the duty belt. The duty belt buckle employs no loose parts that can be lost. Furthermore, the duty belt buckle can easily adjust the circumference of the duty belt without requiring the removal of parts or disassembly.
